And it turns out that they are.&quot;</p><p>An <a href="http://www.wbez.org/tags/invasive-species" target="_blank">invasive species</a> imported from Europe as an ornamental plant, buckthorn has overrun many native ecosystems, including&nbsp;<a href="http://www.wbez.org/blogs/chris-bentley/2013-02/mouse-and-oak-tree-105543" target="_blank">oak savannas</a>&nbsp;and&nbsp;<a href="http://www.wbez.org/blogs/chris-bentley/2013-01/restoring-prairieland-calumets-industrial-corridor-104751" target="_blank">prairieland</a>. Its spindly branches form a dense undergrowth that blocks sunlight from native plants, <a href="http://www.wbez.org/blogs/chris-bentley/2013-03/hacking-back-invasive-species-and-crime-105895" target="_blank">providing cover for crime</a> in some urban corridors. According to the new study, forthcoming in <em>Natural Areas Journal</em>, white-tailed deer were more likely to show up in sites without buckthorn, while coyotes and opossums were more common in sites invaded with buckthorn.</p><p>An Urban Wildlife Institute intern, Marian Vernon, first noticed the trend. Magle encouraged her to see if the data would bear out her observation. Vernon, now a PhD student at Yale University, and her colleagues used motion-triggered infrared cameras to document the appearance of different mammal species at 35 Chicago area sites.</p><p>The study also found seasonal changes in association with buckthorn. Coyotes shifted into sites with buckthorn from spring to summer, affecting the distribution of one of their preferred prey species, white-tailed deer.</p><p>While buckthorn may change the distribution of some mammals, another study suggests it directly harms amphibians.</p><p>Buckthorn emits a chemical called emodin, which has a wide variety of bioactive properties. Previous studies found emodin has laxative properties when eaten by some animals, and is allelopathic, meaning it inhibits the growth of other plant species nearby.</p><p>New research from Northern Illinois University student Allison Sacerdote-Velat and her PhD advisor Richard King found emodin also affects frog embryos, causing fatal kinks in their developing spines. The research is slated to be published in an upcoming edition of the <em>Journal of Herpetology</em>.</p><p>The effects hit native species harder than African clawed&nbsp;frogs, a common test species for environmental toxicity studies. Buckthorn produces emodin in its roots, fruit, bark and leaves, which it drops early in the season to salt the earth, so to speak, against competitors. Buckthorn in Illinois is particularly aggressive in its ability to invade wetlands, strengthening its impact on amphibians who live and breed in those areas.</p><p>The study found high levels of emodin coincided with the breeding activity of several Midwestern amphibian species, including western&nbsp;chorus&nbsp;frogs&nbsp;and blue-spotted salamanders.</p><p>&ldquo;[Buckthorn] litter is probably changing the aquatic invertebrate community,&rdquo; Sacerdote-Velat said. &ldquo;Over time these factors build up and you start losing species diversity.&rdquo;</p><p>The authors of both studies noted the need for further research. Magle pointed out that each study site had only one camera. Small mammals and <a href="http://www.wbez.org/blogs/chris-bentley/2013-04/lakefront-landing-strip-migrating-birds-106429" target="_blank">birds</a> are not big enough to set off the motion-triggered cameras, so it&rsquo;s not clear what effect, if any, buckthorn might have on other species.</p><p>For Magle, the research is a reminder that small ecosystem changes can have cascading effects.</p><p>&ldquo;It shows us that our urban areas are ecosystems,&rdquo; he said, &ldquo;where everything is connected to everything else.&rdquo;</p></p> Mon, 20 May 2013 10:42:00 -0500 http://www.wbez.org/blogs/chris-bentley/2013-05/buckthorn-draws-out-coyotes-cripples-native-frog-development-107271 Blackhawks lose to Coyotes in violent Game 3 http://www.wbez.org/news/blackhawks-lose-coyotes-violent-game-3-98330 <p><p>UPDATE 12:30 p.m.: The Associated Press reports that Raffi Torres, the Phoenix Coyotes forward who knocked the Blackhawks' Marian Hossa out of Tuesday night's game has been suspended indefinitely. Torres is scheduled to face a hearing Friday with NHL officials in New York.</p><p>The Chicago Blackhawks suffered a tough loss Tuesday night in game two of their opening-round playoff series. The Phoenix Coyotes scored in overtime, taking the game 3 to 2.<br><br>It was a violent game at times. Blackhawks forward Marian Hossa was taken off the ice on a stretcher following an upper body blow to the face. The player who dealt the blow, Coyotes' left wing Raffi Torres, was not penalized for the hit.</p><p>The Blackhawks, lead by coach Joel Quenneville, criticized the officiating after Tuesday's game. Quenneville said the refereeing was a disgrace.</p><p>"It was brutal hit," Quenneville said. "You could have a multiple choice question, it's all the above."</p><p>Blackhawks Captain Jonathan Toews said he doesn't know what to expect any more from referees.<br><br>"When there's a guy getting carried off on a stretcher, you'd think that there might be something wrong with what happened. Especially when they're huddled around their goalie in this last game, and he keeps playing and our guy gets three games for it," Toews said, referring to Blackhawks rookie Andrew Shaw, who was recently benched for three games for hitting Phoenix goalie Mike Smith in the second game of this series.</p><p>The Coyotes now lead the series 2 to 1 after last night's win. The two teams are scheduled to face off again for game four on Thursday.</p></p> Wed, 18 Apr 2012 07:29:08 -0500 http://www.wbez.org/news/blackhawks-lose-coyotes-violent-game-3-98330 60 wild coyotes patrol chicago (and occasionally stop at convenience stores) http://www.wbez.org/story/animals/60-wild-coyotes-patrol-chicago-and-occasionally-stop-convenience-stores <img typeof="foaf:Image" src="http://llnw.wbez.org/hoochiemama789.jpg" alt="" /><p><p>This is a coyote "patrolling" the streets (and not just any street, this is State Street!) in downtown Chicago. It's supposed to be there, say the police. And it's not alone.</p><p>Chicago's Cook County now has over 60 coyotes fitted with radio collars (plus a good many uncollared ones) roaming parks, alleys, yards and thoroughfares in one of the biggest cities in America. The animals earn their keep eating small rodents, especially rats and voles. <a href="http://urbancoyoteresearch.com/">The Cook County, Illinois, Coyote Project</a><strong> </strong>calls itself "the largest urban study of coyotes in the world."</p><p><blockquote></p><p>We have tracked the coyotes day and night and located the collared coyotes more than 40,000 times. This allows us to peek into the hidden lives of urban coyotes. We use results from this unique project to answer common questions regarding coyotes in urban areas.</p><p></blockquote></p><p>Their first animal, called "Big Mama" was caught in 2000. "She was a young, transient coyote that was not a member of a group," says Dr. Stan Gehrt of Ohio State who directs the project. By 2002, she had settled down with an uncollared male friend (called, less warmly, "Number 115"), in a heavily-developed area a few miles from O'Hare International Airport. Together Mama and 115 have had at least six litters, producing 45 babies, and those babies now have babies. Big Mama's large family seems to live very discreetly in Chicago. People hardly ever see them.</p><p> </p><p>How do they avoid humans? Well, if you look at the maps, you can see the family spends most of its time hidden in city parks. In this survey, the Yellow Dots show resting spots for Big Mama, and red dots represent 115. If you look closely, it's clear they stick to green spaces. So do their cubs.</p><p>They hunt mostly at night, avoid contact with people, and usually run away from barking dogs, even teeny ones. Stan Gehrt says he's seen small Pekinese house dogs chase coyotes away. Every so often, a coyote has killed a dog or cat, but this is still rare. They like to roam golf courses, municipal parks, public land and their dens are always hidden, often in trees.</p><p>Coyotes are territorial and Chicago now has very distinct coyote neighborhoods. Even Big Mama's family has its own range boundaries. Big Mama, Coyote 115 and their first two children (born in 2006) are represented here by different colors. And as you can see from these radio tracks made in 2007, they often go their own ways.</p><p>Project workers always know where the collared coyotes are. They caught random glimpses of Big Mama. She was seen crossing 8 lanes of traffic on I-290; her male companion often with her. "They are similar to many married couples," the project's website says, "where at times they are inseparable, and other times they take short breaks from each other, but they have defended the same territory together continuously."</p><p>By 2009, Big Mama's radio signal was getting weak. The project (after trying and trying for six months) recaptured her on February 4, 2010. "She was in great condition for a nearly 12-year-old great grandma," Stan Gehrt wrote us. "She weighed about 32 pounds, and had no injuries or illness."</p><p></p><p>Then, in early April, for no special reason ("The only malady the pathologists could fine was kidney failure") the signal stopped moving. Within hours, a project volunteer found her next to a public park. She had died, apparently from old age. Her friend, Coyote 115, has never been recaptured. He's still out there, somewhere in Chicago.</p> &nbsp;<embed type='application/x-shockwave-flash' salign='l' flashvars='&amp;titleAvailable=true&amp;playerAvailable=true&amp;searchAvailable=false&amp;shareFlag=N&amp;singleURL=http://wgntv.vidcms.trb.com/alfresco/service/edge/content/dad1c62c-1807-4eb7-8764-6c19128724bc&amp;propName=wgntv.com&amp;hostURL=http://www.wgntv.com&amp;swfPath=http://wgntv.vid.trb.com/player/&amp;omAccount=tribglobal&amp;omnitureServer=wgntv.com' allowscriptaccess='always' allowfullscreen='true' menu='true' name='PaperVideoTest' bgcolor='#ffffff' devicefont='false' wmode='transparent' scale='showall' loop='true' play='true' pluginspage='http://www.macromedia.com/go/getflashplayer' quality='high' src='http://wgntv.vid.trb.com/player/PaperVideoTest.swf' align='middle' height='450' width='300'></embed><p>While they are masters of discretion, every so often a coyote will break the rules and make contact with humans. The most famous encounter happened in 2007 when an otherwise calm coyote walked into a Quizno's sandwich shop in downtown Chicago, and apparently confused (or hot), hopped into a refrigerated case and sat quietly in the fruit juice section.</p><p>"It wasn't aggressive at all," restaurant manager Bina Patel told the Chicago Tribune. "It was just looking around." Police came and moved that coyote to someplace safer. Probably a park. Copyright 2010 National Public Radio.
